GOAL-OIL BURNER.

Specification of Letters Patent. t t p n 1, 1921 Application filed November 1, 1919. Serial No. 334,916.

To all whom it may concern 7 Be it known that we, Rosana: J. ALKER and Jonn J. SHANE, citizens of the United States, .residing at San Francisco, in the county of San Francisco and State of Cal fornia, have invented a new and Improved Coal-Oil Burner, of which the following is a specification. y

This invention has special reference to oil burners of that type in which the volatile fuel is constantly, under a forced feed, de livered to the burner proper, and primarily our invention has for its purpose to provide an oil burner of the general: type referred to, which is more especially designed for burning coal oil and for domestic uses, which is of a simple and economical construction, that can be readily applied for use in connection with kitchen stoves or ranges and which is adapted for being conveniently handled with perfect safety and which effectively serves its intended purpose.

, Another object of our invention is to provide, in an oil combustion appliance of the kind stated, an improved construction of burner, which, when operatively applied within the fire box, allows for burning up the trash without removing the said burner from the stove or injury to the same.

Again, our invention comprehends, in an appliance as stated, a compact arrangement of the burner which includes a single hollow leg cast with a body that constitutes the oil bowl or holder and which has provision for being easily attached to the fuel supply pipe, which is cast integral with the single leg, the latter having a specially constructed fuel ejector for delivering the fuel onto the bowl and a plug closed opening that provides for cleaning the fuel ejector as conditions may require.

With the above and other objects in view, that will hereinafterbe apparent, our in vention consists in the peculiar features of construction and novel arrangement ofthe parts that constitute the complete burner, all of which will be fully set out in the following detailed description, specifically mentioned in the appended claim and illustrated in the accompanying drawings, in which:

Figure 1 is a diagrammatic view which illustrates our improved oil burner as operatively applied.

Fig. 2 is a cross section of the burner proper, parts being in side elevation.

Fig. 3 is a detail section of the fuel ejecting end of the burner on a. somewhat enlarged scale.

Fig. 4 illustrates, in plan view, several ejector plugs hereinafter referred to.

Fig. 5 is a perspective view of a deflector or flame spreader.

Fig. 6 is a similar View of aslightly modified shape of flame spreader hereinafter specifically mentioned.

While our invention can be used either as a gravity or pressure oil burner, we prefer to construct the parts that constitute the complete appliance, as a pressure burner, since a pressure in the oil tank can always be had where there is city water or in the country from an overhead water tank.

Referring now to the detailed arrangement of the several parts that constitute the complete appliance, 1 designates a tank which may be placed at any desirable point, but preferably in a cellar or an out house.

This tank has a cap filler or pipe 2 at the top through which the oil is fed into the tank.

designates a pipe which opens through the bottom of the tank 1 and which connects with feed pipe 4 that may be a lead from the city water main or an overhead tank, when the appliance is to be used in the country.

Pipe 3 has a valved drain cook 30 and the pipe 4 has a control valve and a back check valve 41, as shown.

5 designates a gage glass that communicates with the top and bottom of the tank for disclosing, at all times, the water level and the amount of oil contained within the tank.

6 designates a valved pipe that connects with the top of the oil tank and which in cludes an angled section 60, which, when the parts are assembled for use, as shown in Fig. 1, passes through the side of the stove. Pipe 6 has. a control valve outside of the stove and an elbow or coupling member 61 for con necting with the burner proper, as is best shown in Fig. 1.

The burner proper, the construction of which is best illustrated in Figs. 1 and 2, consists of a hollow body 7 having a bowl shaped or concaved top and a central with upright boilers, ably a circular pendent boss 71 provided with an internally threaded aperture 72 for screwing onto the coupling 61 on the pipe 60.

8 designates What we term a tubular leg and it extends up from near the upper peripheral edge of the hollow body 7 and, in practice, is fixedly secured to the said body.

The upper end of the leg curves inwardly and terminates in a tubular burner head 81, the lower open end of which projects centrally over the top of the body The aperture in the said lower end of the head 81 is internally threaded to receive any one of a series of ejector plugs 9.

In practice, the orifices in the different plugs 9, are of diflerent sizes or numbers for regulating the discharge from the burner head onto the concaved top of the body or vaporizer 7.

10 is a deflector plate which is used in connection with the burner and, in practice, it rests over the concave top of the hollow body or Vaporizer 7, the said plate being adjustably held over the vaporizer, it having a radial slot the leg 8.

hen using our appliance in connection the plate 10 is preferdisk, as shown in Fig. at.

'l/Vhen, however, the appliance is used in kitchen stoves where a large flame is desired, the deflector isof elongated shape and provided with a slot in one of' its larger sides, as is shown in Fig. 5, it being understood that ineither form, the slotted disk constitutes a flame spreader.

The manner in which our appliance may be used is readily apparent from the drawings taken in connection with the detailed description stated.

To set the same in operative condition, the

11 for slidably engaging with dished top in which the tank 1, assuming the same to be a ten gallon tank, is filled with five gallons of oil. After supplying the oil, the control valve in the water main is opened to permit the water, I

From the foregoing, it will be seen that a:

after lighting the oil fed out from the top of the hollow body 7, the oil, as it passes into the said body 7, is rapidly vaporized and passes off as moist vapor through the ejector end of the burner to constantly feed the generated flame.

lVhen the oil is used up, it is only necessary to close the valve in the water supply or mainpipe and open the drip cock to let out as much water as is needed to give room for another charge of five gallons of oil.

hat we claim is:

In a liquid fuel burner, a burner attachment comprising a hollow body having a bottom aperture for receiving a fuel pipe, and a dished top, a tubular leg that communicates, at one edge of the dished top, with the hollow body and whose upper end terminates in a burner head that discharges onto the dished top, and a deflector plate that is adapted for being placed over the burning fluid is contained, the said plate having an edge notch for engaging the tubular leg, whereby it is held from displacement from the said to 3.
